Also known as insert molding, overmolding is a process in which a product is created using two different types of plastic. This can also be a combination of plastic and other materials such as rubber or metal. To accomplish this manufacturing process, the first material is injected into the mold to provide the base layer for the final product. Once the base layer has been inserted, an additional layer is then added on to the first part, creating the final product.

The use of two materials in one product is not only very efficient, but it also makes the final product more durable. Overmolding lessens the need to assemble and combine two materials or parts together by hand. It can combine them during the manufacturing process itself. Overmolding creates a more durable plastic surface that can last longer, providing higher quality products. The combination of two plastics also makes for stronger and more robust products, which is why overmolding is a manufacturing process that is highly sought-after.
